What is the ratio of area of an equilateral triangle and total surface area of a cuboid where the equilateral triangle is made by taking side equal to the longest rod that can be placed in the cuboid 12 m long, 9 m broad and 8 m high? 1) 289√3 : 2208 2) 17√3 : 36 3) 17 : 29 4) 29√3 : 2208 5) None of these

- 289 root3: 2208
side of triangle = root (12^2+9^2+8^2)=17 m
Area of triangle = ((root3)*17^2)/4 = (289 root3)/4
Area of cuboid = 2*( 108+72+96)=552 sq mtr
Ratio of areas= ((289 root3)/4)/552 = 289 root3/ 2208 or 289 root3: 2208 - 11 years agoHelpfull: Yes(0) No(0)
